The primary object of the invention is to obtain an automatic feed of the material strip, whereby a succession of reports may be made without reloading.

Another object is to construct a device as above stated that is simple in construction and operation, positive in action, assuring a perfect feed of the material strip.-

A further object is that the moving parts in the device are contained within a housing so that the device may be safely and conveniently operated by a child.

A still further object is to accomplish the entire function through the actuation of a piston, whereby the material will be advanced a given distance and securely held.

Other objects and advantages will become apparent as the description proceeds.

Referring to the drawings 10 designates a tubularhousingprovided with cars 11 extending forwardly of the housing 10 and having a carrier 12 perpendicular to the housing and secured to the ears 11 by means of spot-weldingor other suitable means as at 13'. The carrier 12 is substantially U-shaped in cross GHIGAGO, ILLINOIS GUN 1931. Serial No. 539,829.

section, having a front wall 14 and side walls 15 and 16 respectively.

The front wall 14 is provided with a plurality of grooves or ways 17 on either side thereof, and an aperture 18 in'alined relation with the tubular housing 10. The front Wall 14 being spaced from the housing to provide a passageway A for a material strip fed through the passageway A from a supply roll B mounted onthe carrier 12. 60

The housing 10 is provided with a plurality of relatively long depressions 19 to guide a cylinder 20 for endwise movement in the housing 10. Cylinder 20'is somewhat shorter in length than the housing and has a piston 21 slidably mounted therein, with its shaft 22 extending through a cap 23 fixed to the free end of the housing 10. A handle 24 is secured to the piston shaft 21 to reciprocate the piston.

At 25 the housing 10 is: cut away to form guides for the projections 26 of a member 27 secured to and extending from the cylinder 20, to permit the endwise movement of the cylinder in the housing and to prevent the same from turning. The member 27 is also provided with extending ears 28' having a pin 29 on which a material engaging member 80 is pivotally mounted.

A spring 31 coacting with the engaging member and the cylinder to normally hold the engaging member in operative position when the cylinder is spaced from the carrier 12. r

The material engaging member 30 is provided' with upturned flanges 30a to form a guide between the side walls 14 and 15 of the carrier 12 and is also provided with an extension 30?) on either side to extend through cam slots 32-32 in the side walls 14 and 15.

Member 30 is provided at its free end with a plurality of relatively sharp teeth 33 adapted to extend in the grooves 17 when the cylinder 20 is moved in one direction. As the member 30 is moved toward the grooves 17 9 the extension 30?) in the cam slots 32" will allow for a free movement until the extensions 30?) come in contact with the edge 32a of the cam slot 32, permitting the teeth 83to enter thegrooves but preventing them from going into face to face contact with the grooves 17 of the carrier 12 and the teeth will remain in that same relation to the grooves during the entire travel of the engaging member in one direction.

Carrier 12 is provided with relatively short inwardly extending retaining lugs 34: on either side to engage the edge of a material strip that is advanced in the carrier 12. The retaining lugs 3 1 converge toward the front wall 14; (as clearly shown in Fig. 8) and adjacent the retaining lugs the side walls 15 and 16 are provided with inwardly extending guard member 35 to prevent the material strip from becoming disengaged from the retaining lugs 3 1.

At its other end the carrier 12 is provided with a. pin 36 secured tothe wall 16 to carry a roll of fracturable material thereon and a plate 37 pivotally mounted at 38 and the side wall 15 to retain the roll in position.

To protect the hands of the user from contacting the working parts of the device, the

' housing 10 is provided with a guard or plate member 39 extending from and overlying the opening between the guides 25-25.

To operate the device a roll of fracturable material is mounted on the pin 36, the free end being passed between the carrier wall 14 and the housing 10 and the engaging member 30 and the grooves 17 and is brought past the retaining lugs 3 f to rest against the guard member 35. The piston is then withdrawn and as it is forced inwardly, the frictional contact of the piston on the cylinder will cause the cylinder 20 to move with the piston, carrying the engaging member 30 toward the wall 14 of the carrier, perforating the material strip as the teeth 33 on the engaging member enter the grooves 17. At this point extensions 30b of the engaging member come into contact with the edges 32a of the cam slots 32 and the engaging member is then caused to follow the cam surface advancing the material strip until it has been fully advanced and upon further movement in the same direction, the cylinder will hold the material air-tight over the opening in the carrier. Then the piston starts traveling'in the cylinder, compressing the air against the material, causing the sudden breaking of the material and producing a very loud report. This operation may be repeated as often as desired and a series of loud reports will be produced until the supply roll is exhausted.
